KEY FEATURES

• Calculates key system performance indicators:
• Subcooling
• Condensing Temperature Over Ambient (Head Temp) - CTOA
• Approach
• CTOA Goal
• Superheat
• Evaporating Temperature Goal
• Air Psychrometrics:
• Volume
• Density
• Enthalpy
• Dew Point
• Apparatus Dew Point
• Checks for “Un-physical” inputs to help the technician from making Garbage-in, Garbage-out mistakes
• Compares Indicators to a System Performance Model.
• Several predefined models available
• Technician can modify/improve performance models with actual OEM data!
• Model calculates/converts Lennox Approach into Subcooling automatically
• Calculates System Capacity
• Uses Refrigerant Compressor Maps to calculate model performance goals
• Calculates system capacity using Air Mass Flow and change in Enthalpy calculations (corrects for altitude)
• Calculates System Efficiency
• Provides simple forms for data inputs (collected by technician)
• Provides multiple report screens for visual indication of system performance
• Registered version allows the saving and reviewing of tested system data
• Data can be uploaded to an MS Access Database (Palm only)
• Reads data directly from Testo 556/560 using IR print button on the Testo tool
• Allows for objective consistent results - every time, no matter what tools you use
